The ext4 corruption only appears with a combination of unlikely mount options ("nobarrier" and "journal_checksum"; note that "journal_async_commit" implies journal_checksum so I wouldn't worry about it.

ext4 users would be well advised to avoid versions 3.4.14, 3.4.15, 3.5.7, 3.6.2, and 3.6.3; they all contain a patch which can, in some situations, cause filesystem corruption.

What do you think?
